1. Inductance measured at 10 kHz, 0.1 Vrms, 0 Adc using an Agilent/
HP 4132 impedance analyzer or equivalent.
2. DC current at which the inductance drops 10% (typ) from its value
without current.
3. Current that causes the specified temperature rise from 25°C ambient.
4. Electrical specifications at 25°C.
